Determination of temperature fluctuations in a turbulent flow at high temperature by hot-wire anemometry
Abstract
Hot-wire thermal sensitivity coefficients are experimentally determined for turbulent flow temperatures as high as 400 C. The coefficients are used to measure the evolution of temperature fluctuations as a function of the flow mean temperature. The linear evolution of the voltage signal at the hot-wire terminals is confirmed. Studies were conducted at a dynamic pressure of 138 Pa and a current of 1 mA, and plots of the evolution of the voltage signal and the evolution of temperature fluctuations are presented.
